Device for blowing out of a revolving abrasive belt of a belt grinder

摘要

The apparatus (10) for blowing out of a revolving abrasive belt (3) of a belt grinder (1), in particular a wide belt grinding machine,with a nozzle arrangement (20) with a plurality of nozzles sections (22), each comprising at least one nozzle opening (23), wherein the nozzle openings (23) adjacent to one another over the working width of the belt grinder (1) are arranged distributed along an axis,with means for producing a relative movement between the grinding belt (3) and the nozzle arrangement (20),the means to generate the relative movement in such a way that, in the case of a change in the rotational speed of the coated abrasive belt (3) the oscillation frequency and / or the amplitude of the relative movement is changed.
